Adult physiological response to infant cries: effects of temperament of infant, parental status, and gender.

Abstract

This article describes research on adult physiological and self-report response to audiotapes of infants' cries. 3 groups were studied: nonparents, primiparous parents, and multiparous parents. The tapes consisted of cries ordered (difficult, average, easy) according to sound spectrographic features and infant temperament ratings. While nonparents and multiparous parents showed the expected order in arousal levels (difficult infant cries highest, easy infant cries lowest), primiparous parents had highest levels to average infant cries. Overall, primiparous parents had highest levels of arousal, nonparents next, and multiparous parents least. There were no gender differences in arousal. Difficult infant cries received higher irritation and spoiled ratings; were rated as more grating, arousing, piercing, etc.; were less similar to own infants' cries; and were said to be caused more frequently by frustration, etc., rather than routine physical discomfort. Fathers had higher irritation and spoiled ratings, and lower care for ratings, than mothers. The relationship of these data to own infant temperament ratings was also assessed.
